many of the arguments for Brexit were built on lies: about how much the UK paid into the European Union; about how Brexit wouldn’t hurt the British economy. Another problem was that the Brexit campaign was tapping into the same sense of nationalism and nostalgia that the Trump campaign was promoting back home: the days of Churchill, the absence of immigrants and intrusive international institutions. The arguments for staying in the EU were grounded in facts, not emotion: The EU was Britain’s largest market. The EU offered Britain a stronger voice in global affairs.
